Specification of Letters Patent.

Patented May it, 1915.

Application filed June 17, 1911. Serial No. 633,848.

To all whom it may concern Be it known that I, FRED TSGHUDY, a citizen of the United States, and a resident of Birmingham, county of Jefferson, and State of Alabama, have invented certain new and useful Improvements in Coke-Producing Plants, of which the following is a specification.

My invention relates to the art of producing coke and has particular reference to novel apparatus for use in connection with a furnace or oven for producing coke.

(Jo-pending applications covering different features of thaapparatus shown herein have been filed resulting in Patents Nos. 1,069,206 of Aug. 5, 1912 and 1,093,895 of April 21, 1914. An application is also pending, Serial No. 657,454, filed Oct. 30,

In the operation of by-product coke ovens it is the custom to arrange a plurality of such ovens in a battery, often as many as seventy ovens being combined into one coke producing plant. Difficulties have been experienced in the operation of such ovens, particularly when the ovens of the regenerative, reversing type are employed, these difliculties being caused by the deterioration of the checker .work due to deposits of carbon thereon, caused largely by the burning of'the waste gas; and by lack of facilities for the individual regulation of each coke producing unit. Therefore, the purpose and object of the present invention is to overcome these difliculties by means of novel ap paratus such as herein shown and described.

I have found by experiments and otherwise that the cause of the deposition of soot in the checker work of regenerative coke ovens is found in the method of reversing the fur-- naces and for the reason that the distilled gas used in the heating of these regenerative furnaces contains a large amount of free carbon which, if interrupted in its passage to the stack flues, will deposit in the checker work of the furnace. This is caused by the fact that the reversing of the gas and air in the furnace is, in common practice, simultaneous; that is, the products of combustion on their way to the stack-are suddenly arrested, due to the entrance of gas and air to the reverse side of the furnace and when arrested cause a deposit of soot or carbon on the checker work.

One of the objects therefore of the present invention is to provide novel apparatus arranged to overcomethis defective operation and prolong the life of the checker work ofthe furnaces.

Another ob]ect is to provide means in connection with each coke producing unit whereby the stock draft may be individually regulated. It has been the custom heretofore to provide regulating means in the main stack flue, but this regulating means precludes-any individual regulation of the units.

.My invention will be stood by reference to drawings, wherein,

Figures 1 and 2, placed side by side, represent a coke producing plant such as con templated by me; Fig. 3 is a longitudinal section through one' of the coke producing units, showing the parts in detail.

Referring more particularly to the drawings, it will be seen that I provide a plurality of ovens 20, there being any desired number thereof. In the present instance I have arranged for seventy ovens. As shown in F 1g. 3, these ovens include regenerative checker work 21, 22, the fines 23, air inlet or stack outlet ports 24, 25, stack flues 26, 27, and the main stack fine 28. It will be understood that a coking chamber, not shown, extends longitudinally of the furnace and in the plane of the flues 23. Provided on each end of the furnace are gas mains 29, 30. At either end of the furnace and communicating with the gas mains are valves 31, 32, operable by means of lever arms 33, 34, connected to cables 35, 36. As shown, the gas is entered into the furnace heating chamber by means of the nozzles 37, 38. These cables at one end terminate in the counter-weights 39, 40, and at the other end in my novel reversing mechanism.

For the specific description and mode of operation of the air and stack reversing valve reference may be had to my Patent 'No. 1,069,206. The details of the reversing mechanism are shown in my application, Serial No. 657,454.

It is contemplated by me that the operation of the motor for causing the reversal of the furnaces shall be automatically caused by a master clock. In this way the operations are carried on without attention from workmen and insure a uniform product and economical production.

It will be understood that although my novel apparatus is particularly adapted for more readily underthe accompanying use in connection with a by-product reversing coke oven, 1t may be used with any regenerative reversing furnace with slight modifications. It will be also understood that many modifications may be made in the apparatus herein described, all without departure from the spirit of my invention.

'I claim:

1. A; by-product coke producing plant comprising, in combination, a plurality of regenerative, reversible coke ovens, gas valves and air and stack reversing valves applied to both ends of each oven, and mechanical means actuated by a single motor for actuating said'gasfair and stack valves,

said mechanism in its actuation synchronously repeating the actions of discontinuing the supply of gas to one side of each oven, then subsequently and substantially simultaneously reversing the direction of flow of air through each oven, then subsequently admitting a supply of gas from the opposite side of each oven, substantially as described.

2. A by-product coke producing plant comprising, in combination, a plurality of regenerative, reversible coke ovens, I gas valves and air and stack reversing valves applied to both ends of each oven, and mechanical means actuated by a single motor for actuating said gas, air and stack valves, said mechanism inits actuation synchronously repeating the actions of discontinuing the supply of gas to one side of each oven, then subsequently and substantially simultaneously reversing the direction of flow of air through each oven, then subsequently admitting a supply of gas from the opposite side of each oven, and means for regulating the stack draft of each oven, substantially as described.
